ADJUSTAB LE STAND OR CHAIR FOR ARTISANSf SPECIFICATION forming part ofLetters Patent No. 624,567, dated May 9, 1899.

Application filed PebruaryZO, 1899. Serial No. 706,152. (No model.)

To all whom it may concern:

Be it known that I, JULIUS STONE, a citizen of the United States,residing at Boston, in the county of Suffolk and State of Massachusetts,

have invented a newand useful Improvement in Adjustable Stands or Chairsfor Artisans,of which the following is a full, clear, and exactdescription, reference being had to theaccompanying drawings, forming apart of this specification, in explaining its nature.

The invention relates to a stand or chair for the use of artisansemployed on or about the outer wall of a building and which consists inmeans for the attachment of the stand or chair to the building and alsoto means for moving the chair both toward and from the wall lengthwiseit and perpendicularly with respect to it, which means are connectedwith the chair or stand and adapted to be operated from it in any of itspositions.

Referring to the drawings, Figure 1 is a view in front elevation of myimprovement applied to a building. Fig. 2 is a view in side elevationthereof. spective, enlarged, of an adjustable holder, to which referencewill hereinafter be made.

In the drawings, A represents the chair or stand. It may be of anydesired size and of any form of construction. In the drawings I haverepresented it as small and adapted to hold a single person. Ihave alsorepresented it as consisting of a base-piece a, which serves as a flooror support and which preferablyhas a front edge a, which is straight or.parallel with the wall of the building, and a curved side and rear edgea It is also represented as suspended by the three chains a a a two i ofwhich chains, a a are attached to the front corners, and the thirdchain, a is attached to the rear corner. The chains are separated orstrained apart by the strainingframe a, over which the chains extend andupon which chains it is vertically ad j ustable,

being fastened at any elevation from the base a by fastening-screws a.The chains at their upper end are attached to a common unitingblock aand this block has a hook a", which hooks into the eye or shackle b of ablock B, connected by a suspending and hoisting rope I) with a block B,suspended from a trolley O, which is suspended from a horizontal rail D.

The hoisting rope runs through sheaves in Fig. 3 is a view in per-- thetwo blocks B B, and its end is attached to the chair or stand, and itaffords means for the raising, holding, and lowering of the chair orstand by the occupant of the chair.

The rail D is preferably of flat bar iron and is held by the hooks D Dwhich are of a size to hook over the gutter or edge of a roof of abuilding, with which roof the points engage. Each hook has a longdownwardly-extending shank d, which has extending through its lower enda narrow recess d of a size to re ceive an end of the rail D, whichpasses through the said recess (1 and has a removable stop d upon itsouter end. There is also attached to the lower end of each shank a screwstay-rod E, having a threaded section E,adapt-' ed to turn in a threadednut e in the shank to adjust the position of the lower end of the shankwith respect to the wall of the building. The said stay-rod has itsinner ends provided with pointed forks e c, which are horizontallydisposed in relation to each other and which bear against the wall ofthe building and act to stay the lower end of the hookshank. (See Fig.2.) A locking-screw e ,carried by the shank, serves to lock the shank tothe screw stay-rod after the rod has been adjusted, and the stay-rodalsocarries at its outer end an adjustable'collar e, which may screwupon the stay-rod or otherwise be horizontally movable thereon and whichupon the adjustment of the stay-rod is moved against the outer edge ofthe hook-shank and locked against it by a locking-screw e. Thesesuspending-hooks D D are arranged at some distance apart and near theends of the rail D. When required, an additional reinforcinghook D maybe used, This hook is adapted to be movable between the fixed hooks D Dand engages the rail by means of a hook (1 formed on its lower end and.upon which the rail rests. The rail also carries, near each of the fixedhooks, preferably near each end, the adjustable blocks F F, each ofwhich is arranged to slide upon the rail and each of Which is adapted tobe fastened to the rail by a fastening-screw f. Each of these blocks hassuspendedfrom it beneath the rail a roll f, over which a draw-rope fextending in both directions from the trolley C and to the stand orchair A, runs. This rope extends through eyes f on the chair or standand is long enough to extend to the ground, the chair riding upon it,and the portion of the rope beneath the chair or stand is prevented fromtwisting by means of a Weighted separatingarm f having eyes f throughwhich the rope runs, and which separates the rope and a Weight f,attached to its center. The rope f is thus brought to a position topermit the occupant of the chair or stand to use it in drawing thetrolley C and moving the chair or standhorizontally along the wall ofthe building in one direction or the other, according to which branch ofthe rope is pulled. The chair also has attached toit horizontal rods GG, each carrying at its inner end a roll 9, adapted to bear against theWall of the building. These rods are adjustably secured to the chair orstand to permit it to be set in or out with respect to the said wall,and for this purpose the base a of the chair carries on its under sidethe rod-holders g, in which the rods are adjustable and to which theyare fastened in fixed position by a setscrew 9 These rod-holders arenear the sides of the chair or stand, and the rods are thus so locatedas to prevent the chair or stand from twisting or turning on itssupporting-rope.

Having thus fully described my invention, I claim and desire to secureby Letters Patent of the United States 1. In a device of the characterspecified the combination of the rail D, its supportinghooks D, Dthe'trolley O mounted upon said rail, the stand or chair A, thehoisting, supporting and lowering rope b connecting the chair or standwith the trolley, the rolls f adjustably secured to the rail, and thedraW-ropef extending from the trolley C over the rolls and thence to thechair A, as and for the purposes described.

2. The combination in a device of the character specified of the chairor stand A suspended from the rail D vertically and horizontallymovablein relation thereto, and the rail supports or hooks D, D havingdepending shanks provided with holes for receiving the ends of therails, and the-stay-rods E having an adjustable relation to the ends ofthe and vertically movable with relation thereto,

5. In a device of the character specified the combination of the hooksD, D the rail:

D attached to said hooks, the adjustable forked staying-rods E, thetrolley C mounted upon the rail, the adjustable rolls f mounted upon therail, the chair or stand A, the-hoisting, supporting and lowering ropeI) connectin g the chair with the trolley, the trolley-rope f extendingfrom the trolley over said rolls f to the chair andthehorizontally-adjustable rods G carried by said chair or stand.
